Cinnamon Bun Cookies

Instructions

1. In a medium-sized mixing bowl, use an electric mixer to cream together the butter, sugar, vanilla and salt. Add the flour, stirring until the dough comes together. Flatten the dough into a disk, wrap it in plastic wrap, and refrigerate until you're ready to use it (an hour is good).
2. Transfer the chilled dough to a lightly floured piece of parchment or waxed paper. Roll it into a 9x12-inch rectangle. In a small bowl, whisk together the egg white and water until foamy. Brush onto the rolled out dough. In another small bowl, whisk together the sugar and cinnamon. Sprinkle it evenly over the dough. Starting with a long edge, carefully roll the dough into a log, sealing the edge (if dough sticks to parchment, gently use a metal spatula to guide it off of the paper). Wrap in plastic wrap or parchment, and freeze until firm.
3. Preheat the oven to 350°F. Lightly grease (or line with parchment) two cookie sheets. Remove the dough from the freezer and unwrap it. Using a sharp knife, gently cut it into 1/2-inch slices. Transfer them to the prepared baking sheets. Bake the cookies for 12 to 15 minutes, until they're a light golden brown. Remove them from the oven and transfer to a rack to cool.
4. Sift or strain the powdered sugar into a medium-sized bowl to remove any lumps. Whisk the cream into the sugar to make a smooth icing. Drizzle or spread the icing onto the cookies (or serve alongside in a bowl for dipping).
